  • Fully Assembled and Tested for Basic Functionality

Product Details

The MAX20830 evaluation kit (EV kit) is a reference design platform designed for evaluation of the MAX20830/MAX20830T single-output, fully integrated, highly efficient, step-down DC-DC switching regulators with a PMBus™ interface. The MAX20830/MAX20830T have an internal 1.8V LDO output to power the gate drives (VCC) and internal circuitry (AVDD). The devices also have an optional LDO input pin (LDOIN), allowing connection from a 2.5V to 5.5V bias input supply for optimized efficiency. The EV kit is capable of delivering up to 30A to the load. The EV kit package is a fully assembled and tested multilayer PCB implementation of high efficiency and high-power density.

The selection of key converter configuration parameters acting on two external resistors allows the design flexibility to match several application scenario requirements. Refer to the MAX20830 IC data sheet for detailed information regarding the description, features, benefits, and parameters.
